Writing program administrators (WPAs) work in constant negotiation with institutional forces outside of individual control, where the concerns of infrastructure impact writing programs continuously. In periods of transition, where new WPAs are entering a program, or the institution itself is shifting around the established program of a seasoned WPA, the ability to understand and rhetorically act in concert with one's infrastructure can often determine the success of a writing program. In this dissertation, I conduct a mixed-methods examination of the phenomenon of WPA infrastructure, situating infrastructure as a rhetorical lens for understanding writing program administrators' work as they face moments of transition in their career. Through a combination of meta-analysis of a subcorpus of WPA lore and stimulated recall interviews with current WPAs in the field, I form a picture of the phenomenon of infrastructural rhetoric and promote its use as a holistic lens to rhetorically engage with complex institutional systems.
